Given function is

now we need to find the value of k such that function f(x) continuous everywhere.
We know that any function f(x) is continuous at point x=a if left hand limit and right hand limits at the point x=a are equal.
So we just need to find both left and right hand limits then set equal to each other to find the value of k
To find the left hand limit (LHD) we plug x=-4 into 3x+k
so LHD= 3(-4)+k
To find the Right hand limit (RHD) we plug x=-4 into

so RHD= 
Now set both equal





k=-0.47
<u>Hence final answer is -0.47.</u>
You square it so for example the first one would be 1
<em>The given equation is: E=17/20 D , where E=amount of Euros and D= amount of U.S dollar.
</em>
<em>
</em>
<em>Now for 1 U.S dollar, we need to plug D=1 into the above equation. So, we will get.........
</em>
<em>
E=17/20(1)</em>
<em>E=1/20=0.85</em>
<em>0.85 Euros have the same amount as 1 U.S dollar.
